Is there any analog radio receiver that prevents fading of the SW reception?

[prabhatkarpe4]

I have been using AM radio receivers from a long time but I have encountered fading many times while listening to the SW reception. However, I have noticed that the most expensive radio receivers from Tecsun, Degen, and Sony minimize fading up to certain extent. So, why does it happen? Is it something to do with the AGC or the sensitivity?

I would also like to know whether an AM radio that uses vacuum tubes instead of transistors, can have a better reception quality?

do you UNDERSTAND what a discussions forum is and HOW to correctly and politely use it ?

Short wave band fading is an atmospheric (rf skip) phenomenon. You would need antennas many miles apart to mitigate this fading type. The AGC is just an automatic 'volume' control. As a student of any age there is a lot to understand. Many fading types, many frequencies/wavelengths and 100 years of technology to review. It will take time.
